1 Executive Summary
The Demand Activated Manufacturing Architecture (DAMA) project during
the last five years of work with the U.S. Integrated Textile Complex
(retail, apparel, textile, and fiber sectors) has developed an inter-enterprise
architecture and collaborative model for supply chains. This model will
enable improved collaborative business across any manufacturing based
supply chain. The DAMA Model for Supply Chain Collaboration is a high-level
model for collaboration to achieve Demand Activated Manufacturing. The
industry has determined that collaborative business practices are necessary
to provide a significant reduction in time and cost to product pipelines.
Potential savings in the U.S. Integrated Textile Complex (ITC) are estimated
at $45 Billion per year with a realistically achievable 50% reduction
in time.
Collaboration has been recognized as the single biggest
opportunity since Quick Response for Industry. "While many companies
have redesigned internal processes, the leaders are working collaboratively
with trading partners to integrate their processes to eliminate costs
and decrease response time to consumer demand. When these best practices
are fully implemented in the softgoods supply chain, consumers will
save an estimated $48 billion annually" (KSA Report QR From Vision
to Reality).
The Collaboration, Planning, Forecasting, and Replenishment
(CPFR ® ) endeavor, is an initiative to close the business opportunity
gap that exists between todays practices (such as Quick Response)
and the new best practices of collaboration. Randy Mott, CIO and Senior
Vice President, Wal-Mart, made the following comment: I believe
that CPFR ® is the single largest opportunity to move inventory
management forward in the next five years. We plan to implement collaborative
relationships with well over 100 suppliers in the next 12 months. We
believe that CPFR ® is the driver for moving into the next era of
buyer-seller relationships".
"Supply chain collaboration is about companies working
together towards a common set of goals. Essential to success is a joint
agreement spelling out what success is and how issues are to be resolved.
The companies that execute this strategy correctly will recognize significant
immediate and long term benefits" (Jim Lovejoy, DAMA Project Director).
The architecture and model described in this document provide a roadmap
and methodology for executing collaborative business across a Textile
Supply Chain.
Collaborative supply chains will not be successfully implemented
overnight. It will require changes in business practices, and small-scale
proof of concept pilots before they can be implemented successfully
in a large-scale manner. This document describes the following components:
The DAMA Architecture (Figure 1 & 2),
The Demand Activated Manufacturing Inter-enterprise Model (Figure
4),
The DAMA Model for Supply Chain Collaboration (Figure 6) and
The Process for Executing the DAMA Model (Figure 15).
The DAMA Architecture provides a framework for developing business collaboration.
The Demand Activated Manufacturing Inter-enterprise model demonstrates
the requirements for the new type of organizations required to engage
effectively in supply chain collaborative practices. The DAMA Model
for Supply Chain Collaboration provides a recommended set of processes
that could be implemented in a collaborative manner. Moreover, the Process
for Executing the DAMA Model describes a roadmap for establishing a
successful collaborative supply chain.
2. DAMA Architecture
The Demand Activated Manufacturing Architecture (DAMA) project has developed
an inter-enterprise architecture and Collaboration Model for supply
chains that will enable improved collaborative business across the supply
chain. The industry has determined that collaborative business practices
are necessary to provide a significant reduction in time and cost to
product pipelines. The Collaboration, Planning, Forecasting, and Replenishment
(CPFR ® ) endeavor, in which DAMA played an active role provided
the template for this work. DAMAs concern was to include all of
the supply chain sectors and all of the textile industrys functions.
One model defined by DAMA was an architecture model. It was designed
to assist in understanding important collaboration factors and concepts.
This architecture model has five components each with specific definitions.
The architecture model, its components, and associated definitions are
shown in Figure 1 and Figure 2.

Figure 1. Definition of an Architecture
Figure 2. Five Components of the DAMA Architecture
DAMAs Inter-Enterprise Architecture (which spans
multiple companies across a supply chain) is shown in Figure 3. Each
company (enterprise) in a sector may have their own unique internal
architecture for sharing corporate information. The key architecture
for collaboration across the supply chain is the support of a common
set of information available to all members of the supply chain. The
information must be timely, valid, secure and selectively available
with client level authentication. The DAMA technologies have demonstrated
and piloted this kind of architecture.

Figure 3. DAMAs Inter-Enterprise Architecture
3 Demand Activated Manufacturing Inter-enterprise Model
Industry is starting to recognize that the new collaborative paradigm
provides the right answer. Retail demand needs to be synchronized with
manufacturing constraints across multiple companies through collaboration
across the supply chain. In DAMA this synchronization is called Demand
Activated Manufacturing.
The general literature on supply chain collaboration as well as the
information gained from our work directly with the U.S. ITC all point
to the emergence of a qualitatively new type of organization as the
end point of a shift to supply chain collaborative practices. This new
organization is the culmination of a series of changes that begin in
the internal workings of a company, and then (and only then) shift focus
to inter-company relationships. Internal (to a company) functional transparency
and the associated intra-enterprise information exchange structures
and processes must be achieved before the cross-company, inter-enterprise
exchanges that underlie true collaborative relationships can be maximized.
Figure 4 illustrates this movement from left to right, as a company
moves from an internal focus to an ultimate focus on the consumer.

TQM - total quality management / ERP - enterprise resource planning
Figure 4. Demand Activated Manufacturing Inter-enterprise Model
The cultural changes required moving a company from lean
manufacturing to an agile company can be a multi-year and painful process.
The adoption of a series of new business practices and attitudes are
required. Our research on the U.S. ITC, supported by the literature
review conducted for that research, confirmed that the one necessary
piece for the movement to collaboration is industry culture change;
changes in the values and attitudes that motivate behavior will facilitate
the change. . Once the decision is made to modify corporate value structures
and associated activities to support collaborative relationships, a
company may employ tools and methodologies to facilitate the changes.
These tools and methodologies may include maps of information that flows
within the supply chain, collaborative business frameworks, and architecture-based
information systems.
4 DAMA Model for Supply Chain Collaboration
4.1 Understanding As-Is in order to proceed to a To-Be Model
In order for DAMA to understand the complete supply chain, it was
necessary to understand the As-Is information model of the
textile industry today. Typically, a textile supply chain consists of
several manufacturers, each representing a sector of the industry; i.e.
fiber, textile, apparel (sewn products) and retail. A model of the industry
was documented that shows the flow of information between these sectors,
and is represented in Figure 5.

Figure 5. AS-IS Model of U.S. ITC
Information is passed between sectors in the form of Electronic
Data Interchange (EDI) transactions, and typically each sector is customer
focused (fiber focuses on the textile customer), rather than consumer
focused (all sectors focus on consumer demand). Internal to each company
there is a number of business processes that occur (forecasting, planning,
scheduling, purchasing, etc.). In addition, typically, the customer
and supplier in the supply chain have little knowledge of those transactions
that are occurring within the other Trading Partner Company(s).
4.2 TO-BE Model for Supply Chain Collaboration
In order for all members of the supply chain to respond to consumer
demand, a new collaborative paradigm is required. This new paradigm
will provide supply chain visibility of critical information for all
members of the supply chain. The DAMA Model for Supply Chain Collaboration
has been developed to show how all sectors of the supply chain would
participate collaboratively in the major business processes that traditionally
have occurred only within the four walls of a particular company. This
model suggests that retail, apparel, textile and fiber companies within
a particular supply chain share information and collaboratively make
decisions about product development, forecasting, planning, scheduling,
product delivery and expediting orders. This model is documented in
the Integration Definition Function Modeling (IDEF0) format. IDEF0 is
a method designed to model the decisions, actions, and activities of
an organization or system (http://www.idef.com).
Table 1 can be used to interpret the IDEF0 conventions

4.2.1 Collaborative Process Implementation
The DAMA Model for Supply Chain Collaboration is a high-level model
for collaboration to achieve Demand Activated Manufacturing as shown
below in Figure 6. There are four possible collaborative activities
that may be employed in this model:
Define Products
Forecast and Plan Capacity Commitments
Schedule Product and Product Delivery
Expedite Production and Delivery Exceptions
Prior to any collaborative activity, the partners must first develop
business-planning agreements. Once the agreements are in place, for
each of the four collaborative activities, the trading partners must
initialize a Supply Chain Utility, the sixth activity in this model.
The Supply Chain Utility is a set of applications and/or shared data
implemented to support collaborative product definition, forecast visibility,
planning, scheduling, and execution.
This model assumes a collaborative supply chain, with
multiple trading partners, working collaboratively to meet consumer
demand. Trust must exist between all trading partners, and technical
data security must be implemented. Working together, the trading partners
share information about their products, manufacturing capabilities,
allocations of capacity to the partnership, and day-to-day operational
status. Each of these collaborative activities will be discussed in
detail in the following sections.
Figure 6. DAMA Model for Supply Chain Collaboration
4.2.1.1 Collaboratively Develop Business Planning Agreements
Successfully implementing this model requires the trading partners
first complete the process of Collaboratively Develop Business Planning
Agreements. The VICS CPFR ® guidelines thoroughly describe what
is required in the business planning agreements. Where the DAMA collaborative
supply chain diverges from CPFR ® is in the addition of trading
partners from all manufacturing sectors of the supply chain. CPFR ®
was developed to support the relationship between the retailer or distributor,
and the manufacturer (not the entire manufacturing supply chain for
a particular product line). Therefore, the focus of the agreements may
shift from product or category roles in the Joint Business Plan overall
reduction in inventory throughout the supply chain or shared inventory
cost to reduce lead-time for a particular product line. The information
gathered and generated to develop business-planning agreements remains
very much the same.
The DAMA model, like the CPFR ® model, adheres to
management by exception for identifying points of collaboration. The
exception criteria is determined jointly by the distributor / retailer
and manufacturers, and become the factors used to identify items for
collaboration. Figure 7 shows the detailed information that should be
included in the collaborative agreements. This same process is also
a part of the CPFR ® Model published by VICS (CPFR ® Guidelines,
1998 Voluntary Inter-industry Commerce Standards).
Figure 7. Collaboratively Develop Business Planning Agreements
4.2.1.2 Collaboratively Define Products
The concept of collaboratively defining products in a supply chain requires
increased supply chain visibility of all partners to the product lines
in each sector. This model (see Figure 8) requires that all partners
in the chain provide a complete definition of products that they manufacture.
That definition, which will be shared among the partners, will enable
real time product definition. Typically, an order may be one off
from a previous order (i.e. change the knit gauge, the yarn denier or
the fabric finish). If all partners are providing definitions of the
products that they manufacture, then the system can determine in real
time if the manufacturing capability exists to support a new product.
The process to Collaboratively Define Products
begins with customer (consumer) demand. The partnership collaborates
to develop products to meet demand. Once the product is developed, a
product definition is provided to each member in the chain. From that
initial product definition, each partner provides an associated set
of instructions, bill of materials, and capacity allocation to the partnership
to produce the specific product. From this initial information, subsequent
new products can then be defined by querying the Supply Chain Utility
product data to determine the partnerships capability to manufacture
a new product. As subsequent forecasts are developed and orders are
placed, the Supply Chain Utility can determine the partnerships
ability to meet the forecast based on each manufacturers capability
to manufacture, along with their capacity allocation to the partnership.

Figure 8. Collaboratively Define Products
4.2.1.3 Collaboratively Forecast and Plan Capacity
Commitments
The collaborative forecast was first defined by CPFR ® . In DAMAs
model (see Figure 9), one or several partners in the supply chain may
develop the forecast. Once the forecast is developed, it is made visible
to all members through the Supply Chain Utility. Each forecast must
be reflective of the portion of the order that will be filled by each
member in the partnership. The initial loading of the Supply Chain Utility
will ensure that the correct proportions for an order are maintained.
Based on the forecast received, each manufacturing member of the partnership
should then provide a capacity commitment to the forecast for that specific
product line.

Figure 9. Collaboratively Forecast and Plan Capacity Commitments
4.2.1.4 Collaboratively Schedule Product and Product
Delivery
The Supply Chain Utility will balance a final order commitment against
initial capacity commitments. Using that information, in addition to
manufacturing capability data, the utility will generate work orders
for each manufacturer in the supply chain. Each manufacturer then processes
these work orders individually. From their internal information, each
manufacturer generates a ship date (see Figure 10). A complete timeline
for manufacturing the product could be generated from the Supply Chain
Utility (see Figure 11.) The timeline here assumes no inventory is available,
and the ship date at each stage of the process has been calculated by
evaluating the process times provided by each of the manufacturers.
Figure 10. Collaboratively Schedule Production and Product Delivery
4.2.1.5 Collaboratively Expedite Production and Delivery
Exceptions
Manufacturers ship dates generated from the process of collaboratively
scheduling production will be compared to delivery status provided by
each manufacturer on a regular basis. If ship dates and delivery status
for product are not meeting the agreed upon product ship dates, an exception
will occur (see Figure 12). Exceptions may be handled in a variety of
ways. Most exceptions will only be made available to the trading partner
who is initially impacted by the exception. For example, late shipment
of greige goods would trigger an exception for the finishing plant.
Resolution of that exception would either be expedited or negotiated
with the appropriate trading partners. Section 5 provides a description
of the process for implementing this model and resolving exceptions.

Figure 11. Sample Manufacturing Timeline

Figure 12. Collaboratively Expedite Production and Delivery Exceptions
4.2.2 Technical Implementation
This Supply Chain Utility is a concept, and the collaboration processes
illustrate the activities and information associated with the processes,
but they are independent of the architectural implementation of supply
chain collaboration. The technical implementation of these collaborative
processes may be applied in one of several ways.
Ideally, a supply chain utility will support data sharing
through the implementation of software to provide collaborative product
definition, supply chain planning, and supply chain visibility. The
capability to provide secure data sharing is essential. The technical
infrastructure we recommend should follow one of the three infrastructures
recommended by CPFR:
Hub and spoke (Figure 13)
Peer to peer (Figure 14) or
Hosted application (Figure 15).
Figure 13. Hub And Spoke
Collaboration data could be managed in a domain shared
by the trading partners, or it may exist within one of the partners
domains, giving access to the other supply chain trading partners. A
third option would be to employ a third-party service (hosted application).
As with the CPFR ® model, the important point about the illustration
is the agreement on the types and formats of the data being shared and
the nature of the data flows.

Figure 14. Peer to Peer

Figure 15. Hosted Application
4.2.3 Initializing the Supply Chain Utility
The DAMA Model for Supply Chain Collaboration includes a process
where the trading partners initialize a Supply Chain Utility. The manner
in which the Supply Chain Utility is implemented will be determined
by the technical infrastructure selected. It may require the implementation
of software, or initialization of data. The purpose of the utility will
be to support secure data sharing of product definitions, supply chain
planning, and supply chain visibility. The Supply Chain Utility (see
Figure 16) must provide an integration framework to allow a set of generic,
open standards based technology applications to interoperate and provide
collaborative product definition, forecast visibility, planning, scheduling,
and execution of orders. Each of the trading partners will be required
to make information available to the Supply Chain Utility, which will
subsequently be made available to the appropriate trading partners in
the supply chain. The information to be provided must be defined in
the business planning agreements.

Figure 16. Supply Chain Utility
In order for the Supply Chain Utility to be successful,
an ontology, or common industry vocabulary, must be established. The
ontology is a set of formal definitions of the information being shared.
In the textile industry, much of the ontology information can be provided
by organizations such as American Textile Manufacturers Institute
(ATMI). The ATMI has published Voluntary Standards Quality Characteristics
(FASLINK Voluntary EDI Standards, Version 004, Release 010, Implementation
Guide, Quality Characteristics) and Code lists (FASLINK Voluntary EDI
Standards, Version 004, Release 010, Implementation Guide, Appendix
B). The American Apparel Footwear Association (AAFA) Guidelines
for Purchasing by Specification will provide good ontology information
as well (Guidelines for Purchasing by Specification, Apparel Quality
Committee, American Apparel Manufactures Association). However, some
of the ontology will be specific to the partnership, and must be incorporated
in the initial business planning agreements.
The information made available through the supply chain utility would
require each trading partner provide or make available initial information
in the following areas:
manufacturing (lead times, process times, and transport
times),
capacity allocation to the partnership,
manufacturing capability (product lines, bill of material for
products, product specifications, attributes and boundary constraints),
and
exception criteria.
The information provided to the Supply Chain Utility must be protected
in a select, secure manner. Not all partners would necessarily have
access to all of the information. The initial business planning agreements
must define who has access to what information.
Once the initial information is available to the Supply
Chain Utility, the partners must also agree upon the frequency and type
of updates required to support the collaborative relationship. This
information would include inventory levels available to promise for
the partnership, production status, ship status, as well as changes
to the initial data (e.g. a new product line is added, or process times
are increased or reduced).
The success of understanding exception criteria and metrics
measuring the success of the collaborative relationship is highly dependent
on the development of the ontology. For example, is one day late
defined as 8 hours, or 24 hours? Is a day considered a working day?
In a textile supply chain, working days vary through the chainfiber
is processed 24 hours a day, apparel manufacturing may only occur 6
days (Monday through Saturday).
The purpose of the Supply Chain Utility is to provide
supply chain visibility for all partners to the necessary information
they need to meet the goals of the collaborative effort.
5 The Process for Executing the DAMA Model for Supply
Chain Collaboration
Figure 17 shows the proposed execution steps for the DAMA Model for
Supply Chain Collaboration. (Note change capacity to capacity allocation)
Figure 17. Executing the DAMA Model for Supply Chain Collaboration
The Process for executing the DAMA Model for Supply Chain
Collaboration is consumer focused and incorporates all members of the
supply chain. This process can be summarized in Table 2.

Process
Name
|
Description
|
|
1.
|
Develop
Business Planning Agreements |
All
of the information required to execute this step is thoroughly documented
in the CPFR ® Guidelines. It is important that each company accesses
their own strategy, and goals to ensure that these are incorporated
in the partnership agreements. The goal is to arrive at a win-win
situation for all players. This requires sharing of some risk and
rewards, in addition to sharing common goals. |
|
2.
|
Initialize
Supply Chain Utility |
Each
company participating in the collaborative relationship provides
data to support the area of collaboration defined in the business
planning agreements (product definitions, manufacturing capability,
capacity allocations to the partnership, etc.). Providing current
information to the supply chain is an on-going process. Weekly or
daily updates of data might include goods available to promise and
reduction in capacity allocation or capabilities, or changes in
lead times in a process. The technical infrastructure employed with
determine if the data is made available through distributed objects,
loaded onto a central server, or implemented through an XML server
and application. |
|
3.
|
Define
products |
Products
for orders are defined using the data that is loaded in the supply
chain utility. The utility can determine if the product is available;
otherwise, the utility will determine the lead-time required to
produce the product. From this information, the product definition
order is generated. |
|
4.
|
Resolve/Collaborate
on Exceptions for Product Definition |
If a particular product attribute is not available, an exception
is generated. Resolution and/or collaboration of the exception may
involve phone calls, email, or on-line interaction. A company may
decide to add a product or manufacturing capability by changing
their product mix or outsourcing to a third party supplier who is
not a member of this collaborative partnership. |
|
5.
|
Forecast
and Plan Capacity Commitments |
As
consumer demand and forecasts are generated, all members of the
supply chain will have visibility to this information. The supply
chain utility must have information about the allocation of a product
(for example, the partnership agreement guarantees 50% of a product
line to a manufacturer, who in turn guarantees 75% of that same
line to their supplier. According to the estimated forecast, each
supply chain member will commit a certain capacity allocation to
the product line in this collaborative agreement. |
|
6.
|
Resolve/Collaborate
on Forecast or Capacity to Meet Forecast Exceptions |
A
forecast may exceed original capacity commitments or fall short
of the commitments. When this exception occurs, the affected partners
must collaborate and either seek third party sources for an increase
in demand or share associated risk with a reduction in forecasts.
The partnership agreements should provide guidelines for handling
these exceptions to facilitate resolution. |
|
7.
|
Schedule
Production and Product Delivery |
The
supply chain utility, populated with base manufacturing capabilities
and capacity allocation commitments and updated with exception updates
and firm orders, will generate work orders for each of the manufacturers
and a shipment forecast for the carrier(s). Each company will then
process the work order into their internal Enterprise Resource Planning
(ERP) system generating a ship date for the product order. Ship
dates that vary within a specified tolerance of the initial work
orders and retail cancel date will generate exceptions. |
|
8.
|
Resolve/Collaborate
on product Ship Date Exceptions |
Resolving and/or collaborating on product ship date exceptions leads
directly into the expedite production and delivery step. A late
ship date on fiber would impact all customers along the supply chain;
however, the textile manufacturer might have yarn in inventory that
was not previously entered into the supply chain utility (it may
have been reserved for a customer outside of this trading partner
agreement). The supply chain utility processes the updated data
for exceptions. |
|
9.
|
Expedite
production and Delivery |
Visibility
to the supply chain product ship dates allows each member of the
supply chain to expedite production and delivery as it relates to
their position in the chain. Each member of the supply chain will
be providing status updates for the delivery and production status
of the product. |
|
10.
|
Execute
Delivery |
The
carrier, who provides delivery status information (typically an
EDI 214 transaction), handles the execution of delivery. To determine
if target ship-dates are being met, the supply chain utility uses
these delivery status updates. |
6 Future Direction
The DAMA Project has defined an inter-enterprise architecture for
demand activated manufacturing. Through several pilots, the project
participants have identified benefits of data sharing and collaboration
in softgoods supply chains. In order to scale up these supply chain
processes with a large number of suppliers and customers, a supply chain
utility and industry ontology are required.
There are a number of initiatives that the DAMA project
believes will provide the foundation to further develop and complete
the DAMA model for collaboration:
VICS CPFR ® (Collaborative Planning Forecasting
and Replenishment),
VICS CTM (Collaborative Transportation Management),
ATMI (American Textile Manufacturers Institute) Voluntary
Standards (i.e. Quality Characteristics, Codelists),
AAFA (American Apparel and Footwear Association, formerly AAMA)
Guidelines, and
GCI (Global Commerce Initiative).
DAMA has taken work from both CPFR ® and CTM and incorporated it
into the more extensive DAMA model for collaboration. Industry practitioners
will determine the ultimate value of this model. It is the opinion of
the DAMA Project that VICS, ATMI, and AAFA would all be excellent places
to present the model as a possible standard or guidelines for future
collaborative supply chain initiatives.
Collaborative supply chains will not be successfully implemented
overnight. They will require changes in business practices, and small-scale
proof of concept pilots before they can be implemented successfully
in a large-scale manner. The model for collaboration provides a recommended
set of processes that could be implemented in a collaborative way. The
industry standards groups such as ATMI, AAMA, and VICS provide a forum
for developing the industry ontology to support inter-enterprise collaboration.
